された、主面の上方に光を発する発光素子を被う
様にステムに溶接されたキヤンを有し、かつ前記
キヤンの中央は開口され、この開口部はキヤンに
接着剤で接合された透明なガラス板で塞がれてい
る光半導体装置において、前記接着剤がガラス板
の外側表面に広がらない様前記キヤンの開口部内
側に凸部を設けた事を特徴とする光半導体装置。 The can has a can welded to the stem so as to cover a light emitting element that emits light above the main surface, which is indirectly fixed to the main surface of the stem via a block, and the center of the can is open. In an optical semiconductor device in which this opening is closed with a transparent glass plate bonded to the can with an adhesive, a convex portion is provided inside the opening of the can to prevent the adhesive from spreading to the outer surface of the glass plate. An optical semiconductor device characterized by:
